The Casualty Actuarial Society E-Forum is a nonrefereed, electronic journal produced by the Casualty Actuarial Society. The CAS is not responsible for statements or opinions expressed in the papers in this electronic publication. The CAS E-Forum is edited by the Casualty Actuarial Society E-Forum Working Group and CAS staff.

All interested persons are invited to submit papers on topics of interest to the property-casualty actuarial community. Articles need not be written by a member of the CAS, but the paper’s content must be relevant to the interests of the CAS membership.

When submitting an article for publication, E-Forum authors should:

Prepare the following:

a final electronic file of the paper in Microsoft Word or LaTeX. Note: Authors are no longer required to format papers in a specific template.
An accompanying pdf of the final paper.

Separate files for figures in JPEG or PNG format in at least 300 dpi.
Supplementary attachments/datasets (r files, .xls, etc.).

Submit the paper, pdf, figure files, and supplementary attachments/datasets via the CAS Publications submission portal on the ScholarOne website. Through the ScholarOne Author Dashboard, authors are guided through the following seven-step process:

Step 1: Type, Title, & Abstract
Step 2: Attributes
